IMPROVED TOOL-HOLDER..

Specification forming part of Letters Patent No. 42.647, dated May 10, 1864.

.To all whom t may concern:

Beit known that I, WILLIAM W. DRAPER, otl Greeneld, in the county of Franklin and State of Massachusetts, have invented a new 'and Improved Machine for a Tool-Holder 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being nad to the accompanying drawings, in Which- Figurel is a perspective view ot' the instrument. Fig. 2 is a top plan view, the lever being removed to exhibit the shape of the jaw. Fig. 3 is a side elevation of the instru- Fig. 4 is a cross-sectional vien.7 on the line x x. Fig. 5 is a side elevation of the lever.

The nature of my invention consists in the construction ot' a tool holder or handle which may be readily adapted to a variety of tools.

The construction of my instrument is as follows: Attached. to the handle A is a frame or bed-piece, B, provided with the ears b, for the purpose of receiving the lever (l. The bed-piece Band the lever C are so indented as to receive and grasp the tang of any tool not too large for the particular instrument used. The lever C is operated by the set-screw D. The indentations and shape ofthe jaw is such that a tool, either round, square, or dat, may be received and secured with equal facility. (See Fig. 4.)

The mode of operating my invention is too obvious to require particular description.

What I claim as new, and desire to secure by Letters Patent, is-

The bed-piece B and lever C. in combination with and operated by screw D, substantially as shown, and for the purpose set forth.
